Hi, Just wondering if someone has one of these small tabletop cnc mills or can tell me a bit about them? So far all I know is they were made in Concord Ontario, and were used in schools (Googled it), I am guessing around 20-30yrs old (built very heavy). I am thinking of buying one, but I am a little worried about availability of parts (and information). Also what kind of tolerances can I expect from a machine used in school for teaching? Basically I wonder if they cheaped-out on the ballscews & ballnuts?
Thanks
